Abstract
The invention discloses the processing method of clothes goat skin, production is followed successively by pre-treatment, pre- immersion, main immersion, applies grey depilation, liming alkali, fleshing, multiple ash, washing, deliming, softening, secondary washing, pickling；Each step of the present invention carries out at normal temperatures substantially, simple for process, treated goat skin, can carry out the processes such as tanning and dyeing according to the requirement of subsequent garments, hence it is evident that the step of mitigating the processes such as postorder tanning or dyeing increases coloring.
Description
Technical field
The present invention relates to the processing methods of leather, the more particularly, to processing method of the goat skin of clothes.
Background technology
Leather wear is exactly a kind of top-grade consumption from its appearance, is developed so far, leather industry has become in the world
One of indispensable important industry, leather wear become an important branch in current clothes.However, to adapt to the hair of society
Environmental Design, must just be incorporated leather wear by exhibition.The development of the cultivation of raw material skin animal, the implementation of Ecology Leather industry, nothing
One is not to adapt to this environmentally friendly big theme.The variation and amendment of today's society demand ethics, also design for leather wear and bring
New development opportunity.When " environmental protection " becomes a kind of humane symbol in epoch and advocate trend, " Environmental Design " also will be at
For " the in due course label " of Development of Leather Garment Design, while ensureing that environmental goals requires, ensure the due function of product,
Service life, quality etc..Design will not only use the leather fabric of ecological environment-friendly type, more focus on the processing of leather
On, make its service life of product extend as far as possible.
Invention content
Based on the above issues, the present invention discloses the processing method of clothes goat skin, before this method is tanning and dyes
Processing, can require according to the difference to clothes, carry out basis for the specific steps such as follow-up tanning and dyeing, increase coloring；
The technical solution adopted in the present invention is as follows：
The processing method of clothes goat skin produces and is followed successively by pre-treatment, soaks in advance, main immersion, apply grey take off
Hair, liming alkali, fleshing, multiple ash, washing, deliming, softening, secondary washing, pickling；
Pre-treatment：Goat skin is first selected, skin shape is complete, small without disability, position difference, then weighs；
Pre- immersion：It carries out at normal temperatures, liquor ratio 20, bleeding agent and fungicide is added, impregnate 12 hours or more；
Main immersion：It carries out at normal temperatures, liquor ratio 10, skin is put into rotary drum one by one, akali sulphide and bleeding agent, rotation is added
It 10 minutes, goes to 5 minutes within every two hours later, 24 hours total times；
Apply ash depilation：Buttocks and backside high concentration unhairing paste, abdomen apply low concentration unhairing paste；
Liming alkali：It carrying out at normal temperatures, liquor ratio 2, vulcanized sodium, lime, auxiliary liming agent is added, continuous rotation is after 2 hours,
It rotates 15 minutes, then stays overnight per hour；
Fleshing：It is primary in shaving machine upper edge ridge line fleshing, then all over go primary；
Multiple ash：It carries out at normal temperatures, liquor ratio 2, addition lime and auxiliary liming agent, 24 hours；
Washing：First first three times with cold water, 15 minutes every time, reusable heat water first three times, was washed 5 minutes every time；
Deliming：Degreasing agent and ammonium chloride, time 50min is added in 35 DEG C of temperature, liquor ratio 2.0；
Softening：Ammonium chloride and low temperature softening enzyme, degreasing agent, 3.5 hours time is added in liquor ratio 1.5,33 DEG C of temperature
Secondary washing：It is 7.5 that room temperature, which is washed to pH value,；
Pickling：It carries out at normal temperatures, liquor ratio 0.6-0.8, addition sulfuric acid, formic acid, salt, 1.5 hours.
Washing, hot water temperature are 30-35 DEG C.
After deliming, waste liquid temperature should be 30-33 DEG C, and waste liquid pH value should be 8-8.5.
Ammonium chloride and low temperature softening enzyme, degreasing agent are added at one time rotary drum, rotated 3.5 hours by softening.
Processing method of the present invention is simple, and production technology environmental protection, each process carries out at normal temperatures, treated goat skin,
The processes such as tanning and dyeing can be carried out according to the requirement of subsequent garments, hence it is evident that the step of mitigating the processes such as postorder tanning or dyeing,
Increase coloring.
Specific implementation mode
Technical scheme of the present invention described in detail below；The embodiment of the present invention is only for illustrating concrete structure, the rule of the structure
Mould should not be limited by the examples.
